I think that your example is good. I think that you just need one or two more lines in the header describing what it does. Maybe you could put a voxel size of 1.5 if you want to avoid having 1mm = 1voxel. But in general I think that it is good. Actually I think that it should be linked to in the documentation, in building_blocks/data_preparation.html#resampling and the images should be included.
